Patent CA-2358206-A1 (CA)
Inventor: HATAMI-HANZA HAMID
IPC: H04J14/02
Filed: 2001-10-04
Abstract: In an optical access network architecture based on Dense Wavelength Division Multiplexing (DWDM) a central laser source in the central station provides a large number of wavelength channels. Optical interleavers are then used to partition and finally demultiplex the set of available wavelengths to provide one bi-directional wavelength channel per access node, the central station being the only laser source in this network. The laser source provides a large number of very tightly spaced wavelength channels. Each access node retrieves the laser source from the signal received from the central station to be used in modulating its upstream signals. This access network architecture provides one wavelength channel for each access node, and hence enables protocol and data rate transparency on each channel.

Title: Inhibition of stat3 signal transduction for human cancer therapy
Inventor: SEBTI SAID
IPC: A61K45/06
Filed: 2000-01-27
Abstract: Signal Transducer and Activator of Transcription (STAT) proteins have a fundamental role cell signaling, and are activated by a large number of cytokines and growth factors. One member of the STAT family, STAT3, has a critical role in oncogenesis. The present invention relates generally to disruption of the pathway of STAT3 signaling in the treatment of human cancer.  STAT3 activation is shown to be present in diverse tumor cell lines and tumors, to promote oncogenesis, to inhibit apoptosis, and to reduce sensitivity to chemotherapeutic agents. Inhibition of STAT3 signaling induces apoptosis specifically in tumor cell lines, and increases sensitivity to chemotherapeutic agents. The invention relates more particularly to methods, compositions, means of administering such compositions, and means for identifying such compositions for the inhibition of STAT3 intracellular signaling in the treatment of human cancers.

Title: Load control system having an overload protection circuit
Inventor: DEJONGE STUART
IPC: H02H7/20
Filed: 2000-06-13
Abstract: A load control circuit (36) having an overload circuit capable of protecting  a switching element (26) from overload conditions over a wide range of operati ng conditions. The overload circuit limits the maximum average power dissipatio n of the switching element (26) in accordance with a comparison of an average voltage across the switching element over a half-cycle and a variable threshold. The variable threshold is determined based on an ON-state resistance of the switching element (26) and the environment in which the switching elements are operating. The variable threshold accounts for the squared term (V2 or I2) in determining power dissipation and allows power to  be determined based on average voltage.

Patent CA-2375760-A1 (CA)
Title: Method of measuring concentration of luminescent materials in turbid media
Inventor: PATTERSON MICHAEL S
IPC: A61B5/00
Filed: 2000-07-13
Abstract: The present invention provides a method for measurement of concentration of fluorophores in turbid media. The method uses a fluorescence plus reflectance technique to measure quantitatively the iin vivo concentration of a fluorescent drug independent of the tissue optical properties. The method involves using the reflectance measurement as a means of correcting for tissue scattering and absorption in the fluorescence measurement. Light directed to the tissue by means of an optical fiber to excite the fluorophores.  Fluorescence from the fluorophores is measured by another fiber at a distance (D1) from the source in the turbid medium, while the excitation light is simultaneously collected at a distance (D2) from the source. The ratio fluorescence/reflectance will be approximately constant for a fixed concentration of the fluorophore and a judicious choice of D1 and D2, regardless of the optical properties of the tissue. The ratio of fluorescence to reflectance on a tissue sample is compared to a calibration curve for a range of fluorophore concentrations, in order to estimate the in vivo concentration in the turbid medium.

Title: Improved scleral prosthesis for treatment of presbyopia and other eye disorders
Inventor: SCHACHAR RONALD A
IPC: A61F9/00
Filed: 2000-06-07
Abstract: Presbyopia and other eye disorders are treated by implanting within a plurality of elongated pockets formed in the tissue of the sclera of the eye transverse to a meridian of the eye, a prosthesis having an elongated base member having an inward surface adapted to be placed against the inward wall of the pocket and having a ridge on the inward surface of the base extending along at least a major portion of the major dimension of the base. The combined effect of the implanted prostheses is to exert a radially outward traction of the sclera in the region overlying the ciliary body which expands the sclera in the affected region together with the underlying ciliary body. The expansion of the ciliary body restores the effective working distance of the ciliary muscle in the presbyopic eye and thereby increases the amplitude of accommodation.  Introduced is an improved scleral prosthesis for the treatment of presbyopia and other eye disorders. An exemplary prosthesis is adapted for contact with the sclera of an eyeball, and comprises a body having a first end and a second end wherein the body has (i) a planform adapted to expand the contacted sclera to increase the effective working distance of the ciliary muscle of the eyeball, and (ii) means for stabilizing the prosthesis within the surgically formed pocket within the sclera of the eyeball.

Patent CA-2388789-A1 (CA)
Title: System and method for recording pushed data
Inventor: DELPUCH ALAIN
IPC: H04N7/24
Filed: 2000-09-15
Abstract: A method for recording pushed interactive data streams of a program. A pushed data stream is broadcast to a receiving station. The data stream includes one or more data objects. The data stream may also reference to live data objects which are intended for immediate consumption and become obsolete thereafter. The data stream may include a file table and object properties corresponding to the data objects. When the data stream is received by the receiving station, the individual data objects are extracted from the data stream. The data objects, accompanying object properties and the file table are then stored on a storage device. Data objects which are external to the data stream or to the program (e.g., data objects from other carousels) are retrieved and are also stored. Live data objects are not stored, but references to these data objects are stored, so that when the program is replayed, current versions of the referenced live data objects can be used. A program not being recorded may contain data objects which are flagged to be cached which are recorded automatically. Consequently, other programs may subsequently access them from the recording when they are played.
